摘要
用扫描电镜、电子探针等，研究了不锈钢、Q230钢、工业纯铝、工业黄铜等材料对硫酸盐还原菌（SRB）的腐蚀敏感性，结果表明Q23O钢易生长生物膜，其主要腐蚀产物为FeS，以点蚀为主。不锈钢、工业纯铝等材料若有缺陷及残余应力处、有利于细菌生长，黄铜耐SRB腐蚀。化学镀Ni－P和Ni－MO－P可提高Q230钢耐微生物腐蚀能力。
The sensitiveness of metal such as mild steel, stainless steel,aluminum and brass to Microbiologically Induced Corrosion (MIC) which induced by Sulfate Reduced Bacteria (SRB) has been studied. The results show that A3 steel is the most sensitive metal and the biofilms on the surface of coupons are thickes than that's of others,the brass is a resistant metal to MIC. Ni-P amorphous alloys have special chemical properties which have excellent corrosion resistance in MIC of SRB. But the resistance effect of Ni-Mo-P amorphous alloy to SRB is poorer than Ni-P amorphous alloy.
